Scientists accurately measure the probability of electron capture by the neon-20 isotope nuclei for the first time A large international team of researchers has empirically measured the probability of electron capture by the neon-20 isotope (20Ne) for the first time. The team has published two papers in the journal Physical Review C describing their achievement and explaining how their experiments pertain to the decay of intermediate-sized stars. Prior research has shown that at the end of their life, small stars form white dwarfs before dropping their outer layers. And large stars end with a supernova burst, resulting in the formation of a neutron star or black hole. How intermediate stars die has not been so well defined. Prior research has also shown that one of the defining factors that determines which way an intermediate star will die is the rate of electron capture by 20Ne and, as a result, the rate at which fluorine-20 (20F) appears. But until now, the probability of transition by such nuclei had not been accurately measured in a laboratory experiment. In this new effort, the researchers have done just that. The experiments were carried out at the JYFL Accelerator Laboratory in Finland. There, the researchers bombarded a carbon foil with 20F nuclei, forcing them to become embedded in the foil—they then measured the radioactive decay. Next, they calculated the probability of a transition. They report that they found 0.00041 percent of 20F nuclei decayed to 20Ne0+.

Spider-Man-style robotic graspers defy gravity Specially designed vacuum suction units allow humans to climb walls. Scientists have developed a suction unit that can be used on rough surfaces, no matter how textured, and that has applications in the development of climbing robots and robotic arms with grasping capabilities. Researchers Xin Li and Kaige Shi developed a zero-pressure difference (ZPD) method to enhance the development of vacuum suction units. Their method overcame leakage limitations by using a high-speed rotating water ring between the surface and suction cup to maintain the vacuum. "There are many applications of our design, but we think the wall-climbing robot will be the most useful," said Li. "Compared to other wall-climbing robots, the robot with our ZPD-based suction unit achieves surprising improvement in performance". The centrifugal force of the rotating water eliminates the pressure difference at the boundary of the vacuum zone to prevent vacuum leakage. It can maintain a high vacuum pressure inside the suction cup.

AlphaZero learns to rule the quantum world The chess world was amazed when the computer algorithm AlphaZero learned, after just four hours on its own, to beat the best chess programs built on human expertise. Now a research group at Aarhus University in Denmark has used the very same algorithm to control a quantum computer. This research group under the direction of Professor Jacob Sherson has just used the computer algorithm AlphaZero to learn to control a quantum system.The research group at Aarhus University has, via computer simulations, demonstrated the broad applicability by applying AlphaZero on three different control problems that could each potentially be used in a quantum computer. The team was very impressed with AlphaZero's ability to learn, as the lead Ph.D. student Mogens Dalgaard described: "When we analyzed the data from AlphaZero we saw that the algorithm had learned to exploit an underlying symmetry of the problem that we did not originally consider. That was an amazing experience. '' Read more at:https://phys.org/news/2020-01-alphazero-quantum-world.html Original paper: Quantum Information (2020). DOI: 10.1038/s41534-019-0241-0

We should celebrate success and acknowledge hard work. My January good wishes to IAPT fraternity also carried with it a lament that there is low participation in several of our all-India initiatives. This invited a number of comments from readers that I have ignored the many emphatically positive achievements of IAPT. At the very least these comments signal the fact that people are indeed reading the Bulletin so the complaint which our editor Prof. Kushwaha had in this matter, will now be a trifle less acute. The participation in NAEST and NANI has grown several folds over the last decade. It now numbers in the tens of thousands. The Anveshikas are vibrant centers with a large number of teachers participating in discussions on physics and scientific topics as well as in grooming the next generation. The NGPE exams have likewise seen a remarkable rise in participation and number close to ten thousand. Every year it has been followed with further training of selected UG students in camps. I recently returned from the camp at BITS Goa and it was an exhilarating experience. Not to forget the National Student Symposium (NSSP) organized annually in Chandigarh for the last several years and which has seen enthusiastic participation by students nationally. These two are in the crucial undergraduate sector. Besides, as reported in the last EC meeting, several RCs registered a very good participation of students at the regional level essay competitions in 2019. The NSE this year saw a participation of two-hundred-thousand students from all corners of the nation. As we perhaps know these exams lead to the international Olympiads, all the students who return from these international events come back with medals. This year all six school students in the Junior Science Olympiad came back with six gold medals putting India at number one in the world at the high school level. These students were guided by IAPT teachers. Our best students in Junior Science and Physics stand shoulder to shoulder with the very best in the world and IAPT has played a major role in establishing this. The Asian Physics Olympiad is an IAPT managed affair and we have discharged our duties credibly here too. At the regional level we have several centers active – Midnapore, Indore, Jaipur and many others. I deeply apologize if I do not mention them all by name; it would take several pages. A large number of workshops/symposia for students and teachers are held monthly in all parts of the nation. There are only sporadic reports about this in the Bulletin and we do not hear about them. It may be mentioned that at the EC meeting in October 2019 we reversed the order of the agenda and heard the regional council representatives first as an acknowledgement of the significant work done by this silent majority. Finally, criticism is always welcome as it helps us to strive, to struggle and not be complacent. Vijay A Singh President IAPT
